A goddamn shit mission

The Remove The Heart mission of Voeld is the worst goddamn piece of fucked up shit mission in the game. 

It's extremely long, and hopeless for a level 10 character on insanity, which I finally gave up on. But I have pushed through, with great difficulty, with a level 13 and ushior/piranha kit. What makes it so hard is every time you die, the damn developers put you all the way back to the beginning out in the snow. 

So many hours later, I was finally at the last step, go through the door into the hanger. The first time I died. The second time, the door was bugged and wouldn't open, so I had to reload an autosave. When I died the second time, because there are a hell of a lot of Kett in there, I had to go back all the way to the oldest autosave; all the others had a bugged door. Now because I died again, the door won't open at all and there are no more autosaves. I have one manual save that is all the way back to the start of the second half of the mission. So I have to plow through another hour or two of fighting to get back to that fucked up door, with no guarantee it won't fuck up again. And I can't just give up because there is no other way out of the damn room. Unless I just cancel the mission altogether. 

This is really a lazy and shitty way to make a game tougher. Pardon my french, but I wasted a lot of damn hours on this one damn mission.
